WebAfter matrix multiplication the appended 1 is removed. matmul differs from dot in two important ways: Multiplication by scalars is not allowed, use * instead. Stacks of matrices are broadcast together as if the matrices were elements, respecting the signature (n,k),(k,m)->(n,m): WebC = A.*B multiplies arrays A and B by multiplying corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each element of the other array.
